With the move to mariadb I have the following situation: I am not explicitely running mysqld so checking the status with systemctl shows it is inactive. However I am running KDE as my desktop. After doing the suggested install after ensuring that mysqld is stopped: pacman -S mariadb libmariadbclient mariadb-clients and accepting the install of these packages with removal of mysql equivalents, I then find that there is a private instance of mysql running by the KDE desktop: ps -eaf | egrep mysql mike 660 657 0 Mar23 ? 00:00:42 /usr/bin/mysqld --defaults-file=/home/mike/.local/share/akonadi/mysql.conf --datadir=/home/mike/.local/share/akonadi/db_data/ --socket=/home/mike/.local/share/akonadi/socket-home1/mysql.socket mike 9747 761 0 13:39 pts/3 00:00:00 egrep mysql So does any expert know whether a mysql_upgrade is necessary for KDE and if so how does one go about doing that upgrade? Thanks. -- mike c
